This is a very valuable article, as I recently discovered. I have a COM component which works great with VB, VB.Net and ASP but when we had some consultants working with C# and they tried to access it, they started complaining about problems accessing the dynamic components.
With a few minor updates and looking over this article, I was able to show them that it was , in fact, possible to do exactly what they said wasn’t (without a bunch of work).
